One of major issues of Usenet when it existed as a major online force was newsgroup creation. If you were to aspire to create a service that would be as large as, say, Twitter, you would have to deal with that issue as well. To me, it seems the solution would be to give Verified Account holders the exclusive ability to create new newsgroups. That would fix that issue quite well.
You would have the ability to have lots of newsgroups with a very specific subject that would be attached to a specific thought leader. There obviously would be some redundancy caused by this, but I really like this concept. It’s really strong and scales well. It also gives the opportunity to lots of value added features that I think people would really enjoy.
It’s just a really cool concept. It’s a really interesting way of fixing the creation of new newsgroups problem. Of course, there are any number of other UX issues to be addressed. You want to make the service feature rich, but you don’t want to make it so complex that it overwhelms people.
